Question

What is the specific heat gravity of alcohol having a density of 0.79g/ml

Answer 1

I assume you want the specific gravity (relative density) of alcohol with a density of 0.79 g/mL.

Specific gravity = density of substance/density of standard
The usual standard is water @ 4 degrees C which is VERY close to 1 g/mL; therefore, specific gravity = 0.79 g/ml/1.0 g/mL = ?
